Liquid ejection device

A liquid ejection device, comprising:

• a conveyance mechanism which conveys a recording medium in one direction;
• a plurality of liquid ejection heads each having an ejection face which has a plurality of ejection openings for ejecting liquid and faces the conveyance mechanism, the liquid ejection heads being arranged into two rows, in each of which two or more liquid ejection heads are arranged along the one direction, so that the liquid ejection heads do not overlap with one another when viewed from a direction perpendicular to the one direction and parallel to in-plane directions of the ejection faces;
• a plurality of filler plates each of which is positioned adjacent to, in the one direction, at least one of the liquid ejection heads in a same row so as to overlap one of the liquid ejection heads in the other row when viewed from the perpendicular direction;
• a plurality of wipers which wipe the ejection faces of the liquid ejection heads, respectively;
• a holder which holds the wipers;
• a support which supports the holder;
• and
• a movement mechanism which moves the holder in the perpendicular direction so that the wipers move in the perpendicular direction while abutting the ejection faces, respectively, wherein:
• the holder is displaceable in the one direction relative to the support;
• and
• the holder has an intruder which intrudes into a gap between a liquid ejection head and a filler plate adjacent to each other when the holder is moved by the movement mechanism in the perpendicular direction.
